For transmitters rated at a maximum output power not listed above the
recommended separation distance d in metres (m) can be estimated using the
equation applicable to the frequency of the transmitter, where P is the maximum
output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects and
people.
Recommended separation distances between RF wireless
communications equipment
The device is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the device
can help prevent electromagnetic interference by maintaining a minimum
distance between RF wireless communications equipment and the device as
recommended below, according to the maximum output power of the
communications equipment.
